Is it true that the 'happy face' spider is a real species?
Yes. A peer-reviewed genomics paper names the Hawaiian happy-face spider Theridion grallator as a real species, and a scientific report describes a newly discovered happy-face spider species from India. Other passing references also describe the happy-face spider as a real Hawaiian arachnid.
